Rubbish boxer maybe wraps head with type of strap? (11)
I believe the answer is:
jabberwocky
'type of strap?' is the definition.
The definition suggests a singular noun which matches the answer.
'rubbish boxer maybe wraps head with' is the wordplay.
I cannot quite see how this works, but
'with' could be 'w' (abbreviation) and 'w' is found in the answer.
'boxer' could be 'rocky' (boxer in the Rocky films) and 'rocky' is located in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for jabberwocky that I've seen before include "Nonsense poem in Lewis Carroll's Through the Looking Glass" , "Lewis Carroll poem from "Through the Looking Glass"" , "Twas brillig poem" , "Lewis Carroll nonsense poem" .)
